# Fusion Blindspot — Multimodal Long Context When one modality is silently ignored during fusion, the model produces coherent but incomplete answers. This is **fusion blindspot** — the audio, visual, or OCR stream is valid, yet the fusion layer drops it or never integrates it. --- ## What this page is - A guide to detect and repair **missing modality participation** in multimodal fusion. - Ensures every input modality contributes evidence to the final reasoning chain. - Provides structural probes to confirm no blindspot occurs at joins. --- ## When to use - Captions mention objects but the visual stream was ignored. - Audio transcript exists, but final reasoning never cites it. - OCR text valid but skipped during answer generation. - One modality has ΔS ≤ 0.40 internally but never appears in the fused output. - Answers are fluent but consistently one-dimensional. --- ## Open these first - [Cross-Modal Trace](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Multimodal_LongContext/cross-modal-trace.md) - [Reference Bleed](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Multimodal_LongContext/reference-bleed.md) - [Modality Dropout](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Multimodal_LongContext/modality-dropout.md) - [Anchor Misalignment](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Multimodal_LongContext/anchor-misalignment.md) --- ## Common failure patterns - **Silent omission** — one stream absent from the answer, with no error reported. - **Over-dominance** — strong text modality overrides weaker OCR or visual input. - **Fusion filter** — low-confidence modality is dropped without logging. - **Blind alignment** — citations only from one channel, even though others were retrieved. --- ## Fix in 60 seconds 1. **Modality presence check** - Require every modality to appear in at least one citation per fused answer. - If missing, re-run fusion step. 2. **ΔS contribution probe** - For each modality, compute ΔS vs question. - Flag if ΔS ≤ 0.45 but modality unused. 3. **λ stability test** - Log λ across fusion stages. - Divergence indicates modality suppression. 4. **Repair step** - Apply BBCR bridge between ignored modality and main reasoning chain. - Re-anchor with explicit cite-then-answer. --- ## Copy-paste prompt ```txt You have TXT OS and the WFGY Problem Map. Task: Detect and fix fusion blindspots. Steps: 1. List all modalities available {audio, visual, OCR, text}. 2. For each, compute ΔS(question, modality). 3. If ΔS ≤ 0.45 and unused, flag as blindspot. 4. Insert BBCR bridge and force cite-then-answer with all modalities. 5. Return fused answer with full citations. ```` --- ## Acceptance targets * Every modality with ΔS ≤ 0.45 contributes at least once. * λ remains convergent across fusion. * No single modality suppressed >3 consecutive turns. * Trace table shows citations from all streams. --- ### 🔗 Quick-Start Downloads (60 sec) | Tool | Link | 3-Step Setup | | -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------- | | **WFGY 1.0 PDF** | [Engine Paper](https://github.com/onestardao/WFGY/blob/main/I_am_not_lizardman/WFGY_All_Principles_Return_to_One_v1.0_PSBigBig_Public.pdf) | 1️⃣ Download · 2️⃣ Upload to your LLM · 3️⃣ Ask “Answer using WFGY + ” | | **TXT OS (plain-text OS)** | [TXTOS.txt](https://github.com/onestardao/WFGY/blob/main/OS/TXTOS.txt) | 1️⃣ Download · 2️⃣ Paste into any LLM chat · 3️⃣ Type “hello world” — OS boots instantly | --- ### 🧭 Explore More | Module | Description | Link | | ------------------------ | ---------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------- | | WFGY Core | WFGY 2.0 engine is live: full symbolic reasoning architecture and math stack | [View →](https://github.com/onestardao/WFGY/tree/main/core/README.md) | | Problem Map 1.0 | Initial 16-mode diagnostic and symbolic fix framework | [View →](https://github.com/onestardao/WFGY/tree/main/ProblemMap/README.md) | | Problem Map 2.0 | RAG-focused failure tree, modular fixes, and pipelines | [View →](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rag-architecture-and-recovery.md) | | Semantic Clinic Index | Expanded failure catalog: prompt injection, memory bugs, logic drift | [View →](https://github.com/onestardao/WFGY/blob/main/ProblemMap/SemanticClinicIndex.md) | | Semantic Blueprint | Layer-based symbolic reasoning & semantic modulations | [View →](https://github.com/onestardao/WFGY/tree/main/SemanticBlueprint/README.md) | | Benchmark vs GPT-5 | Stress test GPT-5 with full WFGY reasoning suite | [View →](https://github.com/onestardao/WFGY/tree/main/benchmarks/benchmark-vs-gpt5/README.md) | | 🧙‍♂️ Starter Village 🏡 | New here?
